Abstract: Researchers, till now, have faced only 2 variants in demand – time variations i.e. linear and exponential variations. A linear variation shows constant change in rate of demand per unit of time for a product, which is a virtual assumption and will rarely be found in any real industry. To exemplify, the demand for the latest technology spare parts, chips, computers etc increases rapidly contrary to obsolete technology and routine gadgets. Some researchers have also termed these variations in exponential category as increasing or decreasing function with respect to per unit of time. From a researcher view an exponential rate of variation is very high to get actually satisfied be demand in actual market. Hence, a realistic approach matching with the researched theories and the actual market conditions is neither linear nor exponential but a quadratic variation in demand and time showing growth in both up and down directions of demand. The problem is solved and formulated in a model form and elaborated using sensitivity analysis.
Keywords: Linear, Exponential, Inventory, Demand, Quadratic Function.
